It is suggested to choose slightly acidic alkaline or neutral sand powder when selecting land, and plant it as concentrated as possible. Before planting, we should dig the transplanting holes, pig manure, cow dung and other organic fertilizers, and pay attention to the amount of fertilization to avoid root rot.

2, planting points

Choose healthy seedlings with authentic varieties, excellent interface, dark green leaves and developed roots when planting. Put the healthy seedlings in the transplanting hole and straighten them, spread the roots out, and do not directly touch the fertilizer to avoid burning the roots. Cover the soil again, the soil must be compacted and watered again after transplanting, so as to facilitate the survival of the root system.

3. Post-planting management

Potted kumquat can be pruned into a round-headed pagoda after daily pruning, which can greatly reduce the consumption of soil nutrients, concentrate soil nutrients and promote the growth of potted kumquat. After pruning, carbendazim can be sprayed properly for disinfection to prevent bacterial infection of the wound.

Planting management is the key to the survival of seedlings. Crispy kumquat likes to grow in humid environment, but it is afraid of water accumulation. Therefore, watering should be done well within one month after planting, and the watering frequency should be determined reasonably according to climate change. If the paddy field is used for planting, pay attention to drainage to avoid water accumulation in the roots. In addition, during the growth and development of the main stem, attention should be paid to the application of base fertilizer and phosphorus and potassium fertilizer.

4, pest control

Diseases and insect pests will inevitably occur during the growth of kumquat, because kumquat has strong disease resistance and few diseases. The main disease is anthracnose, and the main pest is planthopper, which can be controlled by 5% Bordeaux mixture double-effect spraying, while acaricide, acaricide and pyridaben can be sprayed alternately in the early stage of planthopper.

When pruning the old branches of kumquat, cut off the old branches outside the crown. These old branches have lost their ability to bear fruit and can be cut off from the roots; When pruning the green branches of kumquat, it is generally necessary to grow 2-3 branches and buds from strong to weak on the same root tip, and the branches can be thinned appropriately;

When pruning the bare branches of kumquat, you must cut them off, because the bare branches are too long, which will not only affect the growth of other sparse branches, but also easily grow into brooms at the lower parts of bare branches. Therefore, when pruning, you can generally start pruning from the root;
